The IB Diploma course book for Physics has been thoroughly revised, updated and extended. Still uniquely developed with the IB for the latest (2007) syllabus, the content has remained largely untouched, the main change being the improved page design to allow better access to the content. Option units have been more extensively revised and content is covered more rigorously. All of the features from the first edition have been retained - including the wider aims of the IB through connections to TOK, international-mindedness and the IB learner profile. Data-based question and ideas for practical experiments will encourage active learning and critical thinking. Now in colour, more diagrams and photographs have been included to illustrate the concepts discussed and to place the subject in context. Students will find this book stimulating and engaging. The CD material has been designed to enhance the book content. There are interactive multiple choice quizzes for each chapter to allow students to check their comprehension. Full answers to questions in the book are included. A glossary of terms and equations will help students to link topics and check understanding while spreadsheets and databases allow students to examine physical models and practice data analysis techniques.
